Social interdependence is a key concept in CSCL research. However, investigations of students' positive and negative interdependence during collaborative activities have often relied on self-report, rather than dialogue analysis. Bringing together politeness and social interdependence theory, we assessed "dialogue indicators" of positive…

Math homework is transforming at a rapid rate with the continuous advances in educational technology. Computer-based homework, in particular, is gaining popularity across a range of schools, with little empirical evidence on how to optimize student learning. In the current study, middle school students (N = 143) solved a set of challenging…

The development of numerical abilities was examined in three groups of 5 year-olds: one including 13 children accomplishing a numerical training in pencil-and-paper format (EG1); another group including 21 children accomplished a homologous training in computerized format; the remaining 24 children were assigned to the control group (CG). The…

The study examined the interaction between field dependence-independence (FD/I) and learning with modeling software and simulations, and their effect on children's performance. Participants were randomly assigned into two groups. Group A first learned with a modeling tool and then with simulations. Group B learned first with simulations and then…

In design teaching ubiquitous technologies can offer new ways of situating learning within real world experiences. Yet they require new types of knowledge; both an understanding of how to work with the technology and also an understanding of how to use the technologies to respond to changing contexts such as the place and the people. We sought to…

Teachers and students alike would benefit from self-access materials to free up lesson time for activities requiring live face-to-face interaction, but such materials must first undergo thorough testing and evaluation of their pedagogical effectiveness. The present study is part of an ongoing project to develop a series of self-paced, interactive…

Nowadays, technology is advancing on daily basis and more resources are available for educational purposes. However, there are concerns regarding negative effects it can have on children's development. This research investigates the impact of technology, particularly computers on children's social behaviour. There is considerable amount of…

Contemporary engineers need to become more cognizant and more responsive to the emerging needs of the market for engineering and technology services. Social dimension of Web 2.0 which penetrates our society more thoroughly with the availability of broadband services has the potential to contribute decisively to the sustainable development of…

The purpose of this research was to study an effect of levels of learning ability and types of feedback in an electronic portfolio on learning achievement of students in electronic media production for education subject. The samples were 113 students registered in Electronic Media Production for Education Subject divided into 6 groups : 3 control…

An intervention pre- and posttest design was used to study conditions that facilitate children's self-regulation of problem solving activities. In two studies, children were trained to solve a three disc Towers of Hanoi problem. After training, they were asked to solve the problem, describe how they solved it, and perform a four disc…

This 3-year research project was initiated to demonstrate gaming as a methodology for developing young children's readiness skills for interacting with computers, and to investigate the feasibility of doing research in regular classroom settings. The first year was devoted to designing, making, and refining instructional materials. During the…

This study investigated the attitudes toward statistics of graduate students who used a computer program as part of the instruction, which allowed for an individualized, self-paced, student-centered, activity-based course. The twelve sections involved in this study were offered in the spring and fall 2001, spring and fall 2002, spring and fall…

Teachers' attitudes play a critical role in the effectiveness of technology. The Technology Attitude Survey (TAS) was developed to assess teachers' attitudes toward the general use of technology as an educational tool in the classroom. Reliability and validity of the TAS were investigated. A small pilot study showed high reliability. Pretest and…

The purpose of this study was to investigate the effects of verbal interaction cues and ability grouping within a cooperative learning computer-based program. Two hundred thirty-one eighth graders in a required science class were grouped by ability and randomly assigned to homogeneous lower-ability, homogeneous higher-ability, or heterogeneous…

This paper examines the effectiveness of increasing the confidence of preservice teachers in using technology for personal and instructional purposes as a result of participating in an introductory educational technology course offered at the University of Virginia's Curry School of Education. Course participants attended sections designed for…
